Aiming at the problems, of which distributed generation(DG) access has the influence on the grid voltage, a voltage stability evaluation index (FVSI) considering DG is proposed. The theoretical deduction and analysis process is given. Taking the typical circuit of IEEE33 node as an example, the simulation experiment is carried out in different proportion of DG. Through the comparative analysis of...
In recent years, opinion retrieval attracted a growing research interest as online users' opinions become more and more valuable for market survey, political polls, etc. The goal of opinion retrieval is to find relevant and opinionate documents according to a user's query. Compared with previous lexicon-based generative model for opinion retrieval considering that the sentiment words are equal for...
The new type wearable lower extremity exoskeleton was designed using anthropomorphic mechanical, according to the human walking postures, the static analysis was does on the exoskeleton under different postures, and the stress values was obtained. So the optimize the analysis of external skeletal structure was been, the foundation of study the wearable lower extremity was laid for the further.
In modern computer architecture, memory is an indispensable medium that software and systems relies upon when running on the computer. Messages about memory access could reflect attributes of programs, which should be invaluable with decompilation and security-related fields. This paper presents a novel memory access algorithm-SEA (Static Execution Analysis) for analyzing stripped executables. In...
The combined effects of shunt and luminescence coupling on the measurement artifacts of external quantum efficiency (EQE) are modeled and analyzed for the top, middle and bottom subcells of multi-junction solar cells. The measurement artifacts of a Ge bottom cell caused by the combined effects are explained with the models.
The Sybil attack is exceedingly detrimental and subtle to routing mechanism in ad-hoc network. In this paper we propose a framework in which the vulnerability to the Sybil attack for ad-hoc routing protocol can be modeled in a mathematic approach, and the formal analysis is carried out under our extended strand space mode in order to further analyze the validity of the threats from the Sybil attackers...
Department of Defense Architecture Framework (DoDAF) as a common integrated system architecture specification has already gained the widespread acceptance in the world. However, the limitations of its static descriptive form render it unable to support the further analysis for the dynamic behaves of complex integrated system. Therefore, an executable model is needed to fulfill the requirement of analysis,...
Dispute about conception and research area of knowledge management exists always. In order to distinguish and evaluate about the influence factor of the success or failure of knowledge management project, it is necessary to understand it in the point of system thought and to design an integrated entirely knowledge management framework model that is accepted at large. Firstly, this article starts with...
